WASHING COMPOUND.

No Drawing. Application filed May 9,

My invention relates to the art of cleaning and while it is applicable to the cleaning of all sorts of objects, it is especially applicable to laundry use and its use in this connection will be described hereinafter without, however, thereby limiting the in vention, this use being merely selected as characteristic but not exclusive.

The principal object of my invention is to provide a compound by which fabrics may be washed without. danger of injury either to the goods or the colors thereof and by the use of which dyes which would ordinarily be injured by such washing may be Set or made permanent.

A further object of my invention is to provide a compound by which such fabrics may be washed without l'milingand which will tend to bleach white fabrics and eliminate any muddy colors or stains that would otherwise appear therein.

A further object of my invention is to provide a washing compound which may be used for any purpose for which such compounds are connnonly used and to provide this compound either as a solid or a powder or as a solution, as may be most. convenient to the user.

Further objects and advantages will be made evident hereinafter.

The invention beine incapable of illustration no drawing is annexed hereto.

In the preferred embodiment of my invention I first produce a compound consisting of equal parts by weight of common laundry soap and thiosulfate of soda. I have found that while less than this propor- 1922. Serial No. 559,595.

tion of thiosulfate of soda may be used that if more than an equal part is used, the cllicicncy of the compound falls off very rapidly. If desired, an equal part of washing soda may also be added to the compound.

This compound is then used with the fabric to be washed just as ordinary laundry washing powder is used except that, there is no need of boiling the clothes and they need not be subjected to so much mechanical action such as rubbing to loosen the dirt. The clothes after being washed with my compound are white and clean and any colored clothes are uninjured as to the color, many dies being set by my compound which acts as a mordaut.

In the commerical exploitation of my invcntion my compound may be made up as a soap containing not over fifty percent of thiosulfate or it may be made up as a so utlon of soa 7 and thiosulfate of soda put 1 or wzthot v' 1 oF s While I lave described my compound as being used in laundry work and while it has a very great usefulness when so used, I do not wish to be limited to any such use and desire that the scope of my invention shall be determined wholly by the annexed claim.

I claim as my invention:

A cleaning mixture consisting of: soap and sodium thiosulphate in substantially equal parts.

In testimony whereof, I have hereunto set my hand at Los Ane'cles, California, this 4th day of May, 1922.
